Mapping Method for Fulldome Display

2. The method as claimed in claim 1, wherein the at least one invalid image area of the at least one second image comprises two invalid image areas; in step of incorporating the at least one third image with the at least one second image, the at least one second valid image area of the at least one third image is divided into two valid image sub-areas, and the two valid image sub-areas are respectively incorporated with the two invalid image areas.

3. The method as claimed in claim 2, wherein a number of image pixels in each of the invalid image areas increases in a predetermined direction, and a number of image pixels in each of the valid image sub-areas decreases in the predetermined direction; in step of incorporating the at least one third image with the at least one second image, each of the valid image sub-areas of the at least one third image is rotated by 180 degrees and incorporated with one of the invalid image areas of the at least one second image.

4. The method as claimed in claim 1, wherein in step of converting the original image into the deformed image corresponding to the fulldome display, comprising obtaining an original mapping relation, wherein the original mapping relation comprises a first original mapping relation and a second original mapping relation; the first original mapping relation corresponds to the at least one first image and the at least one first displaying module; the second original mapping relation corresponds to the at least one second image, the at least one third image, and the at least one second displaying module; the first original mapping relation constitutes the first mapping relation; in step of incorporating the at least one third image with the at least one second image, comprising converting the second original mapping relation into the second mapping relation.

5. The method as claimed in claim 4, further comprising storing the first mapping relation into the at least one first receiving device, and storing the second mapping relation into the at least one second receiving device.

6. The method as claimed in claim 1, wherein a number of vertical image pixels of a plurality of image pixels of the at least one third image is smaller than or equal to a number of vertical image pixels of a plurality of image pixels of the at least one second image; a number of vertical image pixels of the image pixels of the at least one intermediate image is equal to the number of vertical image pixels of image pixels of the at least one second image.

7. The method as claimed in claim 6, wherein a sum of the number of vertical image pixels of image pixels of the at least one third image and the number of vertical image pixels of image pixels of the at least one second image is greater than a number of vertical image pixels of the image pixels of the at least one first image.

8. The method as claimed in claim 1, wherein a number of horizontal image pixels of the image pixels of the at least one intermediate image is equal to a number of horizontal image pixels of the image pixels of the at least one first image; a number of vertical image pixels of the image pixels of the at least one intermediate image is equal to a nuber of vertical image pixels of the image pixels of the at least one first image.

9. The method as claimed in claim 1, wherein the at least one second image is located between the at least one first image and the at least one third image.

10. The method as claimed in claim 1, wherein the at least one second image comprises two second images; the at least one third image comprises two third images; the at least one first image is located between the two second images; each of the second images is located between the at least one first image and one of the third images.

11. The method as claimed in claim 1, wherein the number of the image pixels in the at least one second valid image area of the image pixels of the at least one third image is smaller than the number of the image pixels in the at least one invalid image area of the image pixels of the at least one second image; the image pixels of the at least one first valid image area in the at least one intermediate image and the image pixels of the at least one first valid image area are separated by the image pixels of the at least one invalid image area.
